My 5th gen was fine around town, but if you were going up a hill at 70 mph on the freeway, the drone was terrible. I need to see how bad it is before I take that plunge. Maybe it will be better with an A8 too, my last car was M6 so you stayed in 6th gear on the freeway. The A8 might downshift on the grades and ease the drone that way.

I am holding out hope that someone will make a box that I can just drop in. There were a couple of them for the last gen, one from JL and one from you-know-who (initials S T). I think someone will make one eventually. No hurry, I am going to milk every mile out of my bumper to bumper warranty. It's not up until January 2020, so I still have time to wait!

The Bose amp is still installed. The wires carrying signal leaving the bose were cut, and tied off. And the amps connect to those wires (post Bose Amp) and is sending signals to the rest of the speakers. We realized early in the install that we had to keep the factory Amp plugged in as a lot of system information runs through there , including the ANC system. But yes, noise cancellaion is still working. I have heard an incorrectly installed system where noise cancellation was disabled, and the car sounds very different.
